so i'm running ubuntu 12.04 with pg8.3.2 installed on it, i want to upgrade to 9.2.4 using the pg_upgrade. i've followed this steps: 1) download postgres9.2.4 2)configure it and compile it 3) make and install the pg_upgrade and pg_upgrade_support utilities from the pg9.2.4 contrib folder 4) init the pg9.2.4 cluster with: initdb -D /usr/local/pgsql9.2.4/data 5) try to check for compatibilities between the 2 clusters and getting the following error while logged into postgres user account. command>> /usr/local/pgsql9.2.0/bin/./pg_upgrade -b /usr/local/pgsql/bin/ -B /usr/local/pgsql9.2.0/bin/ -c -d /usr/local/pgsql/data/ -D /usr/local/pgsql9.2.0/data/ error>> cannot write to log file pg_upgrade_internal.log Failure, exiting 6) so i decided to move on and just do an upgrade without the -c (check for compatibilities) : 6.1) stop both servers 6.2) run the same command without the -c to upgrade and getting : " this utility can only upgrade to postgresql version 9.2" please enlighten me or give me any advice. -- View this message in context: http://postgresql.1045698.n5.nabble.com/PG-UPGRADE-issues-this-utility-can-only-upgrade-to-postgresql-version-9-2-tp5759509.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
